论文摘要
我们在Helimagnet Ni $ _2 $ insbo $ _6 $的多晶样品上进行了无弹性中子散射实验，以构建自旋汉密尔顿。在$ t_ {n} = 76 $ k以下观察到具有20 meV的带能量的自旋波激发。使用线性自旋波理论，光谱与沿堆叠轴偶联的蜂窝旋转层（$ c $ axis）合理地重现。提出的自旋模型重现了垂直于$ c $轴的磁场引起的唯一晶格。
We performed an inelastic neutron scattering experiment on a polycrystalline sample of a helimagnet Ni$_2$InSbO$_6$ to construct the spin Hamiltonian. Well-defined spin-wave excitation with a band energy of 20 meV was observed below $T_{N} = 76$ K. Using the linear spin-wave theory, the spectrum was reasonably reproduced with honeycomb spin layers coupled along the stacking axis (the $c$ axis). The proposed spin model reproduces the soliton lattice induced by a magnetic field applied perpendicular to the $c$ axis.
